So, is there any word on the availability/price of an upgrade from Mac // to Mac //x. I'm especially interested in the drive upgrade. Robert -- Robert K. Shull University of Oklahoma, Engineering Computer Network att!occrsh!uokmax!rob or sun!texsun!uokmax!rob

I'm especially interested in the drive upgrade. > Robert >-- >Robert K. Shull >University of Oklahoma, Engineering Computer Network The following is paraphrased from Apple's press release about the Mac IIx (by the way, the press release refers to it as the Macintosh IIx, not the Macintosh //x): Apple will eventually offer four upgrade levels for owners of Macintosh II computers: 1) Currently available is a PMMU chip. This provides upgraded memory management for the Mac II. Apple states that "the PMMU chip is required for the A/UX operating system and will be used by future versions of the Macintosh operating system." 2) Available "during the fourth calendar quarter" will be a 1.44MB Floppy Disk Drive Upgrade Kit. It includes including the new drive, system ROMs and the SWIM chip. The kit allows Mac II user to replace an 800K drive with the FDHD or add an FDHD as a second drive. 3) The date for the availability for a Macintosh IIx Logic Board Upgrade Kit was not specified. This kit will provide a Macintosh II user with "both the functionality associated with the built-in MMU and the improved performance associated with the 68030 and the 68882." 4) By using both the Logic Board Upgrade Kit and the FDHD kit, a standard Macintosh II "can achieve full system equivalence with the Macintosh IIx system." The suggested retail price for a 4MB/80MB (RAM/Hard disk) Macintosh IIx system is $9,369. Without a hard disk drive, the suggested retail price of a 4MB/FDHD system is $7,769. The suggested retail price for the Logic Board Upgrade Kit (requiring the trade-in of the current logic board) will be $2,199. The suggested retail price of the FDHD Upgrade Kit is $599; the PMMU chip is priced at $499.

Do you need to purchase the PMMU if you have or are upgrading to a Mac IIx? I was under the impression that the 68030 had the memory management unit built in (like the 80386 chip does). If this is true, I don't know why Apple would list the PMMU as part of the upgrade path from a II to a IIx. Jeff White Drexel University - ECE Dept. rutgers!bpa!drexel!jeff

Does not require a 68851. If your dealer tells you otherwise, he/she is wrong. This is not an official Apple endorsement or statement.

I think the PMMU is for if you want to upgrade your II, not to a IIx, but to a II which can run "future versions of the Mac operating system" which will use a PMMU unit. Also for use in AUX.

I presume it is also possible to get a 68882 only, thus giving faster math
with no other changes. (the '882 is upward compatible with the '881)

(the '882 is upward compatible with the '881) The '882 has bigger exception frames and such, so you have to be careful that coprocessor state doesn't overflow into someplace else. I believe that it is possible to interrogate the FPC as to the size of its frames. Portable applications written with Motorola's guidelines in mind should have no problems, but I don't know if Apple's SANE stuff, for example, will deal with these. The FPU will probably cause more problems than the '030. One example - Sun told us that we couldn't plug in our '882 until we got SunOS 4.0, which presumably has LARGER hard-coded frame sizes. Good luck, everybody! (At CMU, a Mac //x with 4M is $2000 more than a Mac ][ with 1M. I think I'll wait for the NeXT announcement.) -- - Ralph W.
